Creationist definition questions?

a kind for example is a dog. we no there are many kinds of dogs. big , small , long hair ,short hair, long tails , short tails , many different breeds , and many different varieties. but all are still dogs. one could breed any variety to another and come up with a new breed. but you would still have a dog. you would never, ever, get anything other than a dog. seems pretty simple to me. just saying.
